Prediabetes blood sugar levels are a warning sign that your body isn’t processing glucose the way it should. These levels are higher than normal but not high enough to be diagnosed as type 2 diabetes.
Learning what these levels mean, how to monitor them, and when to seek medical advice can help you take control of your health before things get more serious.
What Is Prediabetes?
Prediabetes is a condition where your blood sugar levels are elevated, but not high enough to be diagnosed as diabetes. It’s often referred to as the “gray area” between normal and diabetic blood sugar levels.
Many people with prediabetes don’t show clear symptoms, which is why regular testing is important, especially if you have risk factors like family history, being overweight, or a sedentary lifestyle.

Prediabetes Blood Sugar Levels: The Numbers
To better understand prediabetes, it helps to know what typical blood sugar levels look like. The most common tests used to detect prediabetes are:
| Test Type | Normal Range | Prediabetes Range | Diabetes Range |
| Fasting Blood Glucose | Below 100 mg/dL | 100–125 mg/dL | 126 mg/dL or higher |
| A1C Test (average over 3 months) | Below 5.7% | 5.7% – 6.4% | 6.5% or higher |
| Oral Glucose Tolerance Test (OGTT) | Below 140 mg/dL | 140–199 mg/dL | 200 mg/dL or higher |
According to a research study by J. Jin – JAMA, the prediabetes blood sugar levels category helps doctors identify those at high risk of developing type 2 diabetes.
If your levels fall in this range, you may not have symptoms, but your body is already struggling to keep blood sugar in check.

Why These Levels Matter
When your blood sugar is consistently high, even just slightly it can begin to damage blood vessels and nerves. Over time, this can lead to complications such as:
- Heart disease
- Kidney issues
- Eye problems
- Nerve damage
Catching prediabetes early gives you the chance to reverse the trend. Lifestyle changes such as losing weight, eating healthier, and becoming more active can help bring your blood sugar levels back to a normal range.

Signs You Might Have Prediabetes
Most people don’t realize they have prediabetes because there are usually no obvious symptoms. However, some warning signs might include:
- Feeling more thirsty than usual
- Frequent urination
- Fatigue
- Blurry vision
- Increased hunger
Even if you feel fine, if you’re over 45, overweight, or have a family history of diabetes, it’s a good idea to get tested.

Managing Prediabetes
The good news is that prediabetes can often be reversed with lifestyle changes. According to the DeBakey cardiovascular journal, here are some effective ways to manage your blood sugar:
1. Eat Balanced Meals

3. Lose Weight
Even a 5–7% reduction in body weight can have a big impact on blood sugar levels.
4. Get Enough Sleep
Poor sleep can impact insulin sensitivity and hormones that regulate hunger.
5. Monitor Your Levels
Regular testing at home or through your healthcare provider helps you see what’s working.
By consistently following these habits, many people have brought their prediabetes blood sugar levels back to the normal range and avoided developing type 2 diabetes.

Other times to seek medical advice include:
- Sudden weight changes
- Numbness or tingling in your hands or feet
- Darkened skin around the neck or armpits (a condition called acanthosis nigricans)
- Unusual fatigue after meals
Your doctor can run simple blood tests to check your prediabetes blood sugar levels and assess your risk.

What to Expect at the Doctor’s Office
Visiting the doctor for prediabetes concerns usually starts with a discussion about your health history and lifestyle. You may be asked about:
- Your weight and diet
- Family history of diabetes
- Physical activity levels
- Any symptoms you’ve noticed
Next, the doctor will likely order one or more of the following tests:
- Fasting blood glucose test – You’ll be asked not to eat for 8 hours before this blood draw.
- A1C test – Gives an average of your blood sugar levels over the past 2–3 months.
- OGTT – Involves drinking a sugary solution and measuring your blood sugar before and after.
If your results fall in the prediabetes blood sugar levels range, your doctor will guide you on steps to lower them.
